Our transcription: Gradually, the gas and star dust become more and more concentrated at the center of the nebula, heating up to form a star. The material spinning around a new star flattens into a disc, drawn there by gravity from the equatorial bulge created by the star's rotation. Over tens of millions of years, dust gathers as clumps in the hot disk. These collide and weld together under the influence of gravity, forming larger objects called "planetesimals", which, in turn, come together to form the planets. The precise details of this accretionary process remain unclear. Ultimately, the gases themselves partially crystallize and condense to form balls of ice.
